5 Claims.

This invention relates generally to an adjustable support and more particularly to a swinging pole having a spraying nozzle adjustably mounted thereupon. Also, means are provided 5 for adjustably controlling the position of the spraying pole and means are also provided for regulating the nozzle from a point near the base of the pole.

My invention resides in my novel assemblage l of elements to accomplish eicient spraying by both quickly and properly positioning the nozzle in its most optimum position. Furthermore, the spraying means may be quickly swung to a lower position to permit ready transportation thereof l under the branches of the orchard trees and the like.

Other advantages and features will become apparent as the description proceeds.

1937, Serial No. 130,979

The vehicle III is provided with Wheels I4 and .has a platform I5, on which the operator may stand, attached to one end thereof. See Fig. 1 of the drawings.

As is clearly sho-Wn in Fig. 6, two spaced apart 5 bracket members I6 and I I are fastened to the vehicle I0 above the compartment I2, this compartment housing the prime mover for the liquid.

An angle member I8, see Figs. 2 and 6, carries bracket members I9 and 20, the faces of 10 these angle brackets being located in opposed relationship tc the faces of the brackets, I6 and .I'I. The brackets I9 and 20 rigidly support a semi-circular frame construction 2|, notched as indicated at 22.

A pivot rod 23, having a right angled portion 24 at one end thereof, extends through the bracket members I6, I9, 20 and I'I, and collars 25 and 26, attached as clearly shown in Fig. 6 of the drawings, prevent shifting movement of this pivot rod 23.

A journal member 28 is rotatably mounted upon the pivot rod 23. This journal member 28 carries a pivot 29 which receives a base member 30, equipped with a cap 3| whereby the spraying pole 32, having a terminal boss 33, is revolubly mounted upon the universal joint construction provided by the pivot rod 23, the journal 28 and the pivot 29. A collar 34 is xed to the spraying pole 32 and a sliding and rotatable collar 35 is located immediately thereabove. Springs 36 and 31 are respectively fastened at 38 .and 39 onto the semi-circular frame member 2|. Thesesprings 36 and 31 tend to medially locate the spraying pole therebetween. The pivot 29 is located concentrically with respect to the frame member 2|. p The depending portion 24, of the rod 23, is located as shown in Fig. 1, of the drawings. A relatively long spring 40 is attached at 4| onto one corner of the vehicle and its other end is attached at 42 on the lever member 43, this lever member 43 being a prolongation of the semicircular portion 2|, previously referred to. The lever 43 terminates in a handle portion 44 whereby the semi-circular frame 2| may be swung about the rod 23. A stop 46, see Figs. 1 and 6, limits the upward swinging movement of the spray pole or tower.

'I'he depending portion 24 is fastened at 45 onto the spring 40 and under normal conditions, as shown in Fig. l, the spring 40 is located in a straight line. Upon operation of the member 2|, by means of the handle 44, about the rod 23, the depending portion 24 substantially moves in 55 conjunction with the member 43 and thus the spring 40 is elongated somewhat beyond its normal proportional elongation inasmuch as the path of the spring is extended both axially and in an angular position due to the downward swinging of the lower end of the extension 24. This increases the pulling eilect ci the spring more than proportionally when the spraying pole and its appurtenances are swung to their lower arc' of movement.

The spraying pole 32 extends immediately adjacent the semi-circular member 2| and a collar 50, having a hooked extension 5I, is located around the spraying pole 32, the hooked portion 5I extending around and underneath the member 2|. See Fig. 8. A pivoted locking lever 53, see Figs. 1 and 8, has a locking tooth or lug 54 which may be swung downwardly into the chosen slot 22. Thus it will be apparent that the spraying pole 32 may be swung in an arc about the pivot 29, see Fig. 6, and then locked in position by means of the locking lug 54 entering the desired one of the notches 221. 'I'he springs 36 and 31, as previously mentioned, tend to return the spraying pole 32 to its vertical spraying position whenever the locking means is released.

As shown in Fig. 6, the hose I3, carrying the insecticide, enters inside of the pole 32 and passes upwardly therethrough.

The top of the pole 32 is slit as shown in Figs. 1, 3 and 4. Two of the prongs formed, indicated by numerals 41, serve to protect and shield the hose I3 from branches. Two other prongs are bent outwardly as shown in Figs. 3 and 4, and provide pivotal supports 55 and 56, whereby the nozzle 51 and its associated valve member 58, may be mounted for tilting movement as clearly shown in Figs. 1 and 3.

A double spool member 59, see Figs. 4 and 5, is slidably mounted inside of one of the upwardly extending prongs of the pole 32 and one of the grooves in this double spool receives the bifurcated end 60 of a bell crank lever pivotally mounted at 6|. See Fig. 4. The other arm 62 receives a pivotal attachment 63 of the downwardly extending control rod 64. This rod 64, see Figs. 1 and 2, is slidably mounted at 65 and 66 and is rigidly attached at 61 onto the rod 68 which in turn is operated` by the lever 'I0 pivoted at 1I in a bracket 12. This bracket 12 is rigidly attached to the spray pole.

The bracket 12 also receives a second lever 13, pivoted at 14 thereon and a control rod 15, pivoted at 16, extends upwardly to a pivotal attachment 11 onto the nozzle member 51. As will be clearly seen from an inspection of Fig. 1, operation of the lever 13 will rotate the nozzle to the desired vertical angle about the horizontal pivot 55, 56.

The other groove in the double grooved spool receives one arm of a second bell crank, pivoted at 8l on the member 82, rigidly attached to the valve member 58, and the other arm 83 of the bell crank is received in a collar 84. Movement of the collar 84 operates the control rod 85 of the valve. 'I'hus it will be seen that movement of the rod 64, this being caused by operation of the lever member 10, slides the double spool and this in turn moves the arm 80 of the second bell crank lever and the arm 85 whereby the valve is controlled. Thus the supply of insecticide, which ilows upwardly through the hose I3 to the valve 58, see Fig. 4, may be shut off closely adjacent the nozzle. 'This is much to be desired, inasmuch as it gives instant stoppage of the spray and dribbling is eliminated.

From the above description it will be appreciated that I have invented a construction which is capable of being adjusted to many positions whereby the insecticide or spray may be applied underoptimum conditions. That is, the spray may be directed, toward the various branches and foliage so as to accomplish a maximum spraying effect with a minimum of liquid.

Furthermore, the iiow of the iluid may be shut oiI at a point closely adjacent the nozzle whereby immediate termination of the spray may be had. Thus, waste is decidedly minimized.

For the purpose of illustrating my invention I have shown in the accompanying drawings one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of the instrumentalities as hereinl shown and described.

I claim:
